Etienne Champetier c347755f87 Fix ValidateExpectedRoute with non default routes and nil GW
Using ptp plugin with non default routes, we get the following error
when cri-o call CheckNetworkList():
```
Expected Route {Dst:{IP:198.18.128.0 Mask:ffff8000} GW:<nil>} not found in routing table
```
Using cniVersion 0.3.1 to bypass the check, we can see that the
route is added with a gateway
```
$ ip r
198.18.0.0/17 via 198.18.0.1 dev eth0 src 198.18.3.102
198.18.0.1 dev eth0 scope link src 198.18.3.102
198.18.128.0/17 via 198.18.0.1 dev eth0
```

If GW is nil only check if we have a route with a DST that matches, and
ignore the GW.

Fixes #886

Plugins

Some CNI network plugins, maintained by the containernetworking team. For more information, see the CNI website.

Read CONTRIBUTING for build and test instructions.

Plugins supplied:

Main: interface-creating

  • bridge: Creates a bridge, adds the host and the container to it.
  • ipvlan: Adds an ipvlan interface in the container.
  • loopback: Set the state of loopback interface to up.
  • macvlan: Creates a new MAC address, forwards all traffic to that to the container.
  • ptp: Creates a veth pair.
  • vlan: Allocates a vlan device.
  • host-device: Move an already-existing device into a container.
  • dummy: Creates a new Dummy device in the container.

Windows: Windows specific

  • win-bridge: Creates a bridge, adds the host and the container to it.
  • win-overlay: Creates an overlay interface to the container.

IPAM: IP address allocation

  • dhcp: Runs a daemon on the host to make DHCP requests on behalf of the container
  • host-local: Maintains a local database of allocated IPs
  • static: Allocate a single static IPv4/IPv6 address to container. It's useful in debugging purpose.

Meta: other plugins

  • tuning: Tweaks sysctl parameters of an existing interface
  • portmap: An iptables-based portmapping plugin. Maps ports from the host's address space to the container.
  • bandwidth: Allows bandwidth-limiting through use of traffic control tbf (ingress/egress).
  • sbr: A plugin that configures source based routing for an interface (from which it is chained).
  • firewall: A firewall plugin which uses iptables or firewalld to add rules to allow traffic to/from the container.

Sample

The sample plugin provides an example for building your own plugin.
